I IMPROVEMENT IN' FIELD-ROLLERS.

TO ALL WHOM IT-MAY CONCERN:

Be it known 'that I,'E. F. OLDS, of South Lynn, in the countyof Oakland, and State of 'llfIichigan, have invented certainA new'and useful Improvements in Iield-Rollcrs;I and I do hereby declare` that the following is a full and complete description of the construction and operation oi' the same', reference being had to the acconcpanying drawings, making a part of this specification, in which- Figure 1 is a top View of the roller; v

Figure'2 is an end view of the same. Figure@ is a rear side view. Like letters of reference referto like parts in, the' views.

lhis roller consists of the side-pieces A,iig. 1, mortised orotheriwise secured to the angular ends l?-, rigy '2, and which together constitute the frameworkof the roller. This frame is mounted upon the shaft C, to

which itissecured in a rigid manner. lD D are a pair oflrollcrs', which may be constructed of ironl orwood, f'

and either solid or hollow. These rollers turn upon the shaftl o r axle,`and are kept close to each other by a spring, which may b e either spiral or elliptical. The position of this' spring is shown in iig. 1,`in which E 'is a spiral spring, and E an elliptic one. Fis a disk, fixed to the topot' the frame; G the pole by which the roller is drawn and directed. This pole is pivoted to the centre of the dish-and upon which it turns, as wiil hereafter be shown. H isa lover, pivoted to the side of the pole at the point z. The short' end of this lever catches into a notch cut in the periphery of the disk, and retained there by thelispring I. A not-ch corresponding to the one in which the lcveris secured is'cut on the opposite side ot` the disk, as shewn .n.fig. 3, in Awhich J is the notch Hnving'thus described the several parts ot' the. roller, the operation of the same is as vfollows-z The driver takes his place upon the seat K, and starts in the direction of the work. Iu'order to turn the roller vfor the purpose of re-rolling the ground, the operator draws"thelevcrA H toward him. This removes the short end of the lever from the -notch alluded to. As theteam lis brought around, the pole turns upon the' disk, it being pivotcd to the same, as above said. When theI team has reached the opposite side of the roller the lever catches into the notch referred to in fig. 3, and thereby holds the pole in a proper position, and rigid, for drawing the-- roller. By this it will be evident that the roller is not turned around, but reumins stationary while the pole or tongue is brought about, and thus the roller returns directly ovcrtheground just passed over, without leaving any balks at the end, whichlcannotbe donc with arollerconstructcd.inthe ordinary way. "Should the weight of the roller not, be sufficient for the condition ofthe ground, additionalweights may be used by placing stones T in boxes arranged upon the ends of the roller below the sweep of the p'ole.

The advantage of this roller over others is the facility of turning in order t-o repeat or re-roll theground,

thus saving much time, 'andhtearing up the ground while in the act of turning around the roller. I not having tn turn the roller around a mach larger weight can be used than on the ordinary roller, thus rendering it much more effectual. I

The axis of this roller may be madewith a flexible joint in the'middleyso as to adapt it to nnevenground. Should this kind of axle be used, the box for receiving the stones for the purpose of adding to the weight of the roller is attached'to -one end of a lever that will play up and down between the two rollers. The end opposito to the one on which the box is attached is fastened lto the trarne on the opposite-side with'a joint', S0 that it can move u p and down or ex at the point of atta.chment, while the lever rests upon the axle for its fulcrnm,

rising or fallingin proportionA to the ainount of flexion given to the axle,'as the ground is more orless uneven. The purpose of this -lever and box is to press down the roller on tbeinside ends when'the axle is made flexible'.-

This lever and box, .being placed below thepole ot' theroller,- will not be in the way when the team is tprned.

What I claim as my improvement, and desire to secure lay-Letters Patent, 1 s

1. The diskrF, -pole G, lever H, and spring I, as arranged in relatento a field-roller, in the xnanne'r' substantially as described.

2. Rollers D, spring E, and fra/rue B, in'combination withthe disk F, pole G, lever H,l andsp'ring, in the manner and for the purpose set forth. v l
